Biological Composition of Blood Plasma and Tissue Fluid

Plasma of Blood
- Blood plasma is described as being mostly water, containing a wide variety of substances dissolved within it.
- Substances transported in the plasma include:
  - Ions.
  - Nutrients such as glucose.
  - Waste products.
- Plasma also contains large protein molecules known as plasma proteins, which are transported from one place to another in the body at all times.
Tissue Fluid
- Process of Formation: As blood flows through the capillaries within the tissues, some of the plasma leaks out through the small gaps between the cells in the capillary walls.
- Distribution: This leaked plasma enters the spaces located between the cells of the tissue.
- Composition: Tissue fluid is almost identical in composition to blood plasma; however, it contains far fewer protein molecules than plasma. This is because most protein molecules are too large to escape through the gaps in the capillary walls.
- Red Blood Cells: Red blood cells are not present in tissue fluid as they are too large to escape the capillaries.

Fundamentals of Table and Document Formatting

Table Definitions
- Table: Consists of rows and columns.
- Purpose: Used to organize and present text, numbers, and graphics in an easy-to-read manner, making information look more organized.
- Cell: Defined as a box in a table where information is entered.
Table Modification and Tools
- Applied Tools:
  - Font size and Font style.
  - Table resizing.
  - Table design.
  - Shading (used to change the background color of a cell).
  - Borders and Border painter.
  - Text alignment.
- Text Alignment: Refers to the way text is positioned horizontally or vertically within a cell to keep the table organized.
- Merging and Splitting:
  - Merge Cells: A feature used to combine two or more cells into one.
  - Split Cells: Used to divide a single cell into multiple smaller cells.
  - Split Table: Used to break a table into two separate sections.
Tab Navigation in Word Documents
- The main tabs available in Microsoft Word include: File, Home, Insert, Design, Page Layout, References, Mailings, Review, and View.
- Layout (Table) Tab Groupings: Includes Table, Draw, Rows and Columns, Merge, Cell Size, Alignment, and Data.
Document Formatting
- Definition: Formatting documents involves areas such as layout, font, alignment, margining, bulleting, numbering, pictures, graphs, and page orientation.
- Benefits:
  - Documents (such as assignments and essays) look clearer and more organized.
  - Formatted texts are more reader-friendly.
  - Provides consistency through paragraph alignment, line spacing, and visual graphics.

Principles and Features of Electronic Mail (E-mail)

Introduction to E-mail
- E-mail stands for Electronic Mail.
- It is used for sending and receiving messages and attachments (including files, images, sound, and movies) over the internet.
Advantages of E-mail
- Speed: Mail is sent and received around the world in seconds.
- Forwarding: Multiple copies of a message can be sent simultaneously to a group of people.
- Cost: Emails are free as long as the user has an internet connection and an email account.
- Receiving Messages: People do not have to be present at their computers to receive an email.
- Environmental Impact: Helps the environment by reducing the need to use paper.
Common E-mail Service Providers
- Google (Gmail).
- Yahoo (Yahoo Mail).
- Microsoft (Microsoft Outlook).
Structure of an E-mail Address
- An email address is comprised of three parts:
  - Username (e.g., $pema2026$ ).
  - At Symbol ( $@$ ).
  - Domain Name: The name of the email provider (e.g., $gmail.com$ , $education.gov.bt$ ).
- Top-Level Domains:
  - ` $.com$ ightarrow $\text{company}$ .
E-mail Features
- Inbox: Contains read and unread messages.
- Sent: Contains messages that were successfully delivered.
- Compose: The option used to write a new message.
- Draft: Contains messages that may not have been completed.
- Bin/Trash: Contains unwanted or deleted emails.
- Spam: Contains unwanted email advertisements.
E-mail Etiquette
- Always read the email before replying.
- Use proper spelling, grammar, and punctuation.
- Do not write in capitals: This is considered screaming and is disrespectful and unprofessional.
- Keep emails short and concise.
- Do not use "Reply to All" unless absolutely necessary.
Basic Parts of an E-mail Message
- Subject line (should be clear to identify the main topic).
- Sender and Recipient.
- CC (Carbon Copy): Used to send copies to others.
- BCC (Blind Carbon Copy): Used to keep recipients' email addresses private from one another.
- Salutation/Greeting.
- Email Body.
- Closing (e.g., "Best regards," "Sincerely," "Thank you," "Yours Truly," "Respectfully").
- Signature Block (Name, Class, ID, School name).
- Attachments (Additional files like photos and documents).

Information Literacy and Source Evaluation

Components of Information Literacy
- Searching for Information.
- Evaluating Sources.
- Managing Information.
- Using Information Ethically.
- Communicating Information.
Searching Techniques
- Keywords: Search using only important and relevant words.
- Filters: Narrow results by time, type, or source for better accuracy.
- Advanced Search: Use quotation marks (e.g., $\text{"phrase"}$ ) to find exact words or phrases quickly.
Evaluating Sources (The CRAAP Test)
- Currency: Check if the information is recent and up to date.
- Relevance: Ensure the information is useful and related to your specific topic.
- Authority: Examine the author of the information to determine if the source is reliable.
- Accuracy: Confirm the information is correct and supported by evidence.
- Purpose: Identify why the information was created (to inform, educate, sell, or persuade).

Computational Logic: Boolean Operators, Loops, and Iteration

Boolean Operators
- NOT Operator: A boolean operator that reverses the result, changing $\text{true}$ to $\text{false}$ and $\text{false}$ to $\text{true}$ .
- Unary Operator: An operator that takes exactly one value as an input (e.g., the NOT operator).
- Binary Operators: Operators that typically take two inputs (e.g., AND and OR operators).
- Inequality Operators: $<$ (less than) and $>$ (greater than) evaluate relation between two operands and return a boolean value.
  - Example: $\text{health} < 100$ evaluates to $\text{true}$ if health is below 100.
Loops and Iteration
- Iteration: The process of repeatedly executing a block of code until a specific condition is met.
- Until Loop: A type of loop that repeats a block of code until a specific condition becomes true. The computer checks the condition at the start of each iteration; if false, the loop continues.
- For Loop: A loop used to iterate over a sequence (e.g., $\text{For b in bananas}$ ).
Coding Logic Examples
- Monkey Health Scenario:
  - Goal: Regain health until it reaches 100.
  - Algorithm:
    1. Start
    2. Go to Health Zone
    3. Regain health
    4. Go to Banana
    5. End
  - Code: $\text{goto healthZone}$ $\text{until health() == 100: wait()}$ $\text{goto banana}$
- Rotten Fruit Scenario:
  - Code: $\text{For b in bananas:}$ $\text{if not b.rotten(): goto b}$

Questions & Discussion

Q: What does "text alignment" in a table cell mean?
- A: Text alignment is the way you position text horizontally or vertically within a cell to make the table organized.
Q: Why is it important to format tables neatly when presenting information?
- A: It is important because neat information makes the audience understand it easier.
Q: How many inputs do AND and OR operators take?
- A: They usually take two inputs.
Q: What is the health status of the monkey?
- A: Based on the challenge diagrams, the monkey's health is either 80/100 or 40/100 depending on the specific starting point shown.
Q: Karma wants to send the same invitation email to 20 classmates but does not want them to see each other's emails. Which feature should he use?
- A: He should use BCC (Blind Carbon Copy) because it keeps the recipients' emails private. If he used CC, there would be a privacy error where emails are exposed to everyone who received the message.
Q: What might happen if you use too many different fonts in one document?
- A: It will look unprofessional, distract the reader, and theoretically, some computers might struggle to process them.
Q: Identify at least two differences between Document A and Document B.
- A: 1. Document B has bulleting while Document A doesn't. 2. Document A is white in color while Document B is brown.
Q: List one similarity between the two documents.
- A: Both documents have borders.
